I've been to Bangkok numerous times at this stage, and this has been the best accommodation I've stayed in. Sarintip is a wonderful host, and the staff at the condo are lovely too.
The location is great, with street food around the corner and a very short walk to the Thonglor BTS.
There's also a full gym on the top floor with a view of the city while working out, and the pool is great for relaxing too.
The condo itself is cozy and the desk space + wifi makes it comfortable space if you want to work from home.
Will happily book here when visiting Bangkok again.
